BOT'ILE CAP.

Application filed March 4, 1920. Serial No. 363,107.

To all whom it may concern:

Be it known that I, GEoRcE A. IVILLIAMs, a citizen of the United States. residing at- Decatur, in the county of Macon and State of Illinois, have invented a certain new and useful Improvement in Bottle Caps. of which the following is a full. clear, and exact description, reference being had to the accompanying drawlngs.

This invention relates generally to bottle caps and more particularly to one capable of being used over and over again for sealing the mouth of the bottle and without impairment to the cap and with this object in view the invention consists in the details of construction hereinafter fully described and pointed out in the claims. In the drawings forming a part ofthis specification Fig. 1 is a view showing the component parts of the bottle cap detached; Fig. 2 is a perspective view of the completed bottle cap; Fig. 3 is a vertical sectional view of the same; and Fig. at is a vertical sectional view showing a slightly modified form of construction. In the practical embodiment of my invention I employ a thin sheet metal cap A having a depending skirt which is slotted at B providing a plurality of depending skirt portions and in practice I prefer to have one of said depending portions C somewhat deeper and wider than the rest. In connection with the cap having the depending slotted skirt- I employ a divided spring metal ring D which is connected to the lower edge of the depending skirt by rolling the edges of the depending portions around said wire as shown at E and the large depending portion is rolled about the ring at the dividing point ofsaid ring and being wider and deeper than the other sections the roll will be correspondingly larger and consequently will provide a convenient point for applying pressure to the cap in order to remove the same from the mouth of the bottle.

In Fig. -1 I have shown the larger portion and when once applied will be retained in position by the inherent elasticity of the elastic ring and sheet metal slotted skirt and in being forced over the mouth of the bottle the spring ring will yield slightly and in so yielding it will be noted that the movement of the ring ends away from and towards each other will take place entirely within the roll of the portion C. In this manner the ends of the spring ring will alwaysbe protected. A cap of the kind described can be quickly and easily applied to the mouth of the bottle and when so applied will effectively close and seal the same and having preferably a liner G of any suitable ma-- terial applied to the interior of the cap. This cap can be used in connection with bottles or containers which are not intended to withstand pressure but which are intended to receive inert liquids. The cap can be quickly and easily removed by applying pressure upwardly to the enlarged roll owing to the construction of the same and as with which it can be removed. The device can be used over and over again to effectively close and seal the mouth of the bottle.

Having thus described my invention. what I claim is:

1. A bottle cap comprising a slotted skirt and a divided spring ring surrounding said skirt. the lower edges of said slotted portions being rolled about said ring. one of said portions being of greater dimensions than the other portion and rolled about and enveloping the meeting ends of the ring. said larger rolled portion projecting laterally from the skirt to provide a member for the application of pressure.

2. A bottle cap of sheet metal and having a depending slotted skirt. one portion of said skirt being of greater dimensions than the other portions. a divided spring ring surrounding said slotted skirt. the lower ends of the slottedportions being folded around said ring. the larger portion of the slotted skirt being rolled one or more times around the meeting ends of said ring, said rolled portion projecting laterally from the skirt and providing a member for the application of pressure.

In testimony whereof. I hereunto afiix my signature.

GEORGE A. WILLIAMS.
